Figure 3From: Patterned growth of carbon nanotubes over vertically aligned silicon nanowire bundles for achieving uniform field emissionSEM views of CNT-SiNW bundle arrays. (a) Top and cross-sectional SEM image of SiNW bundle array protected by patterned PR template (after catalyst/SiNW removal step) and (b) cross-sectional SEM view of as-realized CNT-SiNW bundle array, indicating that CNTs are grown only atop SiNW bundles.Back to article page
